Test bed and testing method for air atomization coating spray gun spraying testing

Abstract

The invention provides a test bed for air atomization coating spray gun spraying testing. The test bed is used for testing the spraying performance of an air atomization coating spraying gun. The test bed is characterized by being provided with a working test bed which comprises a plurality of spray gun fixing supports arranged on the table board of the working test bed, a spraying plate vertically arranged on one side of the working test bed and provided with a plurality of spraying regions corresponding to the spray gun fixing supports one to one, a spraying distance adjusting mechanism connected to the two sides of the working test bed and the spraying plate, a spray gun driving portion used for providing stable air pressure for an air atomization coating spray gun, a high-speed camera arranged on one side of the working test bed and used for photographing and recording the spraying testing process of the air atomization coating spray gun, a spraying data collection portion used for collecting air consumption data and air pressure data of the air atomization coating spray gun and transmitting the data to a computer, and a light shading plate which has the deep background color and is arranged on the side, away from the high-speed camera, of the spraying plate.

Description

technical field [0001] The invention relates to a spraying test bench and a test method, in particular to a spray test bench and a test method for testing an air atomized paint spray gun. Background technique [0002] The air atomized paint spray gun is a spraying tool used in automobile manufacturing, household manufacturing, etc. After years of research and development, the design technology of spray guns in foreign countries is relatively mature, and the price of its products in China is bound to be expensive. However, the development in this area in my country is relatively slow, basically imitating foreign products, and there is an urgent need for design theory. And method guidance, and this requires the corresponding spray gun test bench. Most of the spray test benches currently on the market are test benches for pesticide spray testing and engine fuel injector atomization effect testing. Experienced workers hold a spray gun to spray the sprayed board, and then judge ...

AI Technical Summary

Problems solved by technology

[0003] The existing test bench for pesticide spray test and engine injector atomization effect test cannot be used for spray gun spray test

However, with the manual test method, the test results are rough, and it is impossible to accurately determine important spray gun performance parameters such as paint rate, spray gun air consumption, spray distance, spray mist width, fog distance, particle size, spray pressure, etc., and cannot realize mechanization and integration. standardized test
